GLM.score_obs(params, scale=None)[source]#

Score first derivative of the log-likelihood for each observation

Parameters:

paramsndarray: Parameter at which score is evaluated.
scaleNone or float: If scale is None, then the default scale will be calculated. Default scale is defined by self.scaletype and set in fit. If scale is not None, then it is used as a fixed scale.

Returns:

score_obsndarray, 2d: The first derivative of the log-likelihood function evaluated at params for each observation.
